摘要
Coronavirus disease 2019(COVID-19)has posed a serious threat to global public health with its rapid spread,high fatality,and severe burden on health care providers all over the world.Although COVID-19 has been established as a respiratory tract infection,it can manifest with gastrointestinal symptoms as a consequence of direct infection by the virus or due to inflammation-mediated cytotoxicity.It has been observed that COVID-19 patients presenting with gastrointestinal symptoms tend to progress to a severe form of disease with increased morbidity and mortality,thus indicating the need for timely management.COVID-19 manifests with a wide spectrum of radiologic findings on gastrointestinal tract imaging,encompassing bowel abnormalities,hepato-biliary and pancreatic involvement,vascular occlusion,and solid organ infarction.Early recognition of these imaging features can facilitate timely treatment of COVID-19 associated gastrointestinal tract complications and may prompt the diagnosis of COVID-19 in patients with atypical disease manifestations.The aim of this article is to provide an overview of the various gastrointestinal imaging manifestations that can be encountered in patients with COVID-19,with an emphasis on early diagnosis of the disease as well as treatment related complications.
